如图是统一3D预训练方法PonderV2(point cloud pre-training via neural rendering),也是以前PonderV1(论文“Ponder: Point cloud pre-training via neural rendering“)的扩展;直接用RGB-D渲染图像的监督进行训练,用于各种室内或室外3D下游应用,例如3D目标检测、3D语义分割、3D场景重建和图像合成等。 如图是PonderV2的...
PonderV2预训练模型拥有强大的三维场景理解能力,得益于统一的以三维渲染为核心的预训练方式。研究者们在11项基准全面测评了PonderV2预训练模型在不同的三维理解任务中的表现,涵盖室内场景理解和室外自动驾驶应用场景、三维场景语义分割和三维场景目标检测、全数据和数据受限情况等。评测结果显示,PonderV2预训练模型在以上的...
